Perdido Watershed Water Quality Improvements and Restoration Assessment Program RESTORE Council Activity Description General Information Proposal Sponsor: Alabama Department of Conservation and Natural Resources (ADCNR) Title: Perdido Watershed Water Quality Improvements and Restoration Assessment Program Project Abstract: Alabama, through the Alabama Department of Conservation and Natural Resources (ADCNR), is requesting $1.5M in Council-Selected Restoration Component funding for the proposed Perdido Watershed Water Quality Improvements and Restoration Assessment Program. This would include planning funds as FPL Category 1. The program will support the primary RESTORE Comprehensive Plan goal to restore water quality and quantity through activities to coordinate the location and sequencing of selected restoration projects in the Perdido Watershed that could be expected to improve water quality and habitat, as well as restoration assessment program to monitor the potential collective impacts to water quality of the co-located projects and other restoration projects within the watershed. Located in Southern Alabama and Northwest Florida, the Perdido Watershed covers approximately 1,100 square miles and is dominated by the 63 mile-long Perdido River. This watershed plays a critical role in the health of the ecosystem of Southeast Alabama and Northwest Florida. The components of the watershed, including the tributaries, floodplains, bayous, and wetlands of the Perdido provide water quality and quantity protection through healthy floodplains, which store and disperse runoff from storms and recharge aquifers. In addition to the anticipated benefits of improved water quality and habitats, this program could also serve as a model for future restoration assessment efforts on the Gulf Coast. Program duration is 3 years. FPL Category: Cat1: Planning Only Activity Type: Program Program: Perdido Watershed Water Quality Improvements and Restoration Assessment Program Co-sponsoring Agency(ies): N/A Is this a construction project?: No RESTORE Act Priority Criteria: (I) Projects that are projected to make the greatest contribution to restoring and protecting the natural resources, ecosystems, fisheries, marine and wildlife habitats, beaches, and coastal wetlands of the Gulf Coast region, without regard to geographic location within the Gulf Coast region. Priority Criteria Justification: #1 Projects that are projected to make the greatest contribution. This program proposes to coordinate and subsequently assess the potential cumulative benefits of restoration activities in a chosen watershed/subwatershed in order to maximize water quality benefits in a way that is potentially measurable outside of an individual project footprint. Habitat loss as well as potential changes in water 1 Draft FPL 3b Activity Description 09/29/2020 quality are two stressors associated with changes in land use as watersheds like the Perdido develop into more urbanized areas. Projects that address existing and potential water quality impacts would provide significant benefits, especially when considered in the context of the size of the watershed. Project Duration (in years): 3 2 Draft FPL 3b Activity Description 09/29/2020 Goals Primary Comprehensive Plan Goal: Restore Water Quality and Quantity Primary Comprehensive Plan Objective: Restore, Improve, and Protect Water Resources Secondary Comprehensive Plan Objectives: Improve Science-Based Decision Making Process Secondary Comprehensive Plan Goals: N/A PF Restoration Technique(s): Improve science-based decision-making processes: Comprehensive planning Reduce excess nutrients and other pollutants to watersheds: Agriculture and forest management Reduce excess nutrients and other pollutants to watersheds: Stormwater management Reduce excess nutrients and other pollutants to watersheds: Wastewater system improvements 3 Draft FPL 3b Activity Description 09/29/2020 Location Location: Proposed activities would be located within the Perdido Watershed near the Perdido River in Baldwin County, Alabama, and potentially Escambia County, FL. HUC8 Watershed(s): South Atlantic-Gulf Region(Choctawhatchee-Escambia) - Florida Panhandle Coastal(Perdido) State(s): Alabama Florida County/Parish(es): AL - Baldwin FL - Escambia Congressional District(s): AL - 1 FL - 2 4 Draft FPL 3b Activity Description 09/29/2020 Narratives Introduction and Overview: Located in Southern Alabama (70 percent of the watershed) and Northwest Florida (30 percent of the watershed), the Perdido Watershed covers approximately 1,100 square miles and is dominated by the 63 mile-long Perdido River, which provides most of Perdido Bay’s freshwater (NWFWMD 2017b). The watershed includes floodplain forests, hydric pine forests, longleaf pine forests, and freshwater wetlands. The major land uses for the Perdido Watershed are diverse, with evergreen and deciduous forests making up most of the central and Upper Perdido, crop lands dominating in the southwest and northern portions, and developed land centered primarily in the southeast. The Alabama portion of the Perdido consists of forested uplands (59.9%), agricultural lands (25.1%), wetlands and open water (8.8%), other (6.2%), with Perdido Bay land use consisting of 27.3% forested uplands, 30.6% agricultural lands, 33.2% wetlands and open waters, with 8.9% other (including urbanized, transitional and barren uplands) (ADCNR 2016). Driven by the diversity of habitats present in the watershed, including riparian and freshwater wetland habitats, estuarine habitats and marine/coastal habitats the Perdido is home to thirty threatened, endangered and/or protected plant species including the White-top pitcher plants (Sarracenia leucophylla) and a number of animals including the Perdido Key Beach Mouse (Peromyscus polionotus trissyllepsis) the Reticulated Flatwoods Salamander (Ambystoma bishop) and the West Indian Manatee (Trichechus manatus latirostris) (NWFWMD 2017). Proposed activities: This proposal contemplates a multi-member program to coordinate the location and sequencing of all or a subset of individual member projects (and other restoration projects) in the Perdido Watershed that could be expected to improve water quality and habitats. It also proposes a restoration assessment program to monitor the potential collective impacts to water quality and habitats of the co-located projects, and/or other funded restoration projects in the watershed. Proposed activities include: 1. Identification of one or more subwatersheds in the Perdido area to support coordination of restoration actions in the watershed as well as the development of watershed scale indicators to track restoration progress. This work will be coordinated by ADCNR and will be open to participation from other Council members and potentially to select stakeholders in the watershed. Given the relatively small scale of the watershed, the entire Perdido watershed may be selected in lieu of one or more subwatersheds. 2. Identification of individual member projects within the subwatershed, that have been or will be implemented in the Perdido watershed, with an emphasis on the selected subwatershed(s). Project type include but are not limited to: agriculture and silviculture BMPs, riparian buffer restoration, habitat acquisition and enhancement, wastewater and stormwater improvements, living shorelines, etc. Projects funded by other restoration funding sources will also be identified and utilized in the development of the restoration progress tracker, discussed in Item 3. 3. Development of a restoration assessment/restoration progress tracker to better understand the potentially collective impacts of restoration projects in the watershed/subwatershed. Outputs potentially include the development of one or more conceptual models, short-term and long-term indicators and a restoration progress tracker/monitoring framework. There are five goals within the RESTORE Councils comprehensive plan. This Program addresses one of those goals, Goal #2: Restore Water Quality and Quantity. The Program ties in with RESTORE Councils primary objective of Restore, Improve, and Protect Water Resources as well as Science to Support Decision-making. This goal is applicable to the proposed activities because a number of the projects being implemented or proposed for implementation in the watershed are expected to provide water 5 Draft FPL 3b Activity Description 09/29/2020 quality benefits. This program will support the identification of benefits at a scale larger than the individual project level. The Perdido watershed was identified as a priority geographic area in the Council Planning Framework and supports the Restoration Approach to Reduce excess nutrients and other pollutants to watersheds Under the 2016 Comprehensive Plan update the Council advanced the following commitments: • Regional ecosystem-based approach to restoration: Through extensive collaboration engagement opportunities as a result of the CPS support funds, it is clear that water quality is a priority goal for the Restore Council members from Florida to Texas. Addressing water quality degradation and impairment is a foundational component of restoring/enhancing a host of living and coastal marine resources. • Leveraging resources and partnerships: FPL3a included a project to purchase and conduct habitat restoration on 10000-12,000 acres in the watershed. That project serves as an anchor for a watershed- scale effort to conduct water quality and habitat improvements in the Perdido Watershed. Finally, Alabama is proposing a water quality improvements program via another proposal, and one or more

(1) Use classifications utilized by the State of Alabama are as follows: Outstanding Alabama Water ................... OAW Public Water Supply ......................... PWS Swimming and Other Whole Body Shellfish Harvesting ........................ SH Fish and Wildlife ........................... F&W Limited Warmwater Fishery ................... LWF Agricultural and Industrial Water Supply ................................ A&I (2) Use classifications apply water quality criteria adopted for particular uses based on existing utilization, uses reasonably expected in the future, and those uses not now possible because of correctable pollution but which could be made if the effects of pollution were controlled or eliminated. Of necessity, the assignment of use classifications must take into consideration the physical capability of waters to meet certain uses. (3) Those use classifications presently included in the standards are reviewed informally by the Department's staff as the need arises, and the entire standards package, to include the use classifications, receives a formal review at least once every three years. Efforts currently underway through local 201 planning projects will provide additional technical data on certain waterbodies in the State, information on treatment alternatives, and applicability of various management techniques, which, when available, will hopefully lead to new decisions regarding use classifications. Of particular interest are those segments which are currently classified for any usage which has an associated Supp.

July/August 2012 Volume 25 Number 4 Jackie Lane - Editor www.friendsofperdidobay.com What A Difference Dilution Makes With the deluge the Pensacola area experienced on June 9th, the drought that was plaguing this area, was finally broken in a big way. Thirteen to 20 inches fell in one day at certain areas close to the bay. Less rain fell in the northern part of the watershed. The few rains we have had this past Spring were not really sufficient to break the year long drought. Before the June 9th rain, the Perdido River was at very low flow. Any type of man-made pollution entering Perdido Bay would not get sufficient dilution and toxic substances (what ever they are) would increase in the bay. This is especially true of paper mill effluent from International Paper, which during times of low flow of the Perdido River, can constitute one-fifth of the flow of the Perdido River. Because of the very concentrated pollution of paper mill effluent, especially high levels of organic chemicals and organic nitrogen, paper mill effluent needs to be greatly diluted in order not to cause harm. This spring there was a dearth of life in the bay. A 2-liter plastic bottle placed in the upper bay, had no barnacles growing on it after three weeks in the bay.

  • Baldwin County Storm Surge Atlas
    Baldwin County Hurricane Surge Atlas Baldwin County Emergency Management Agency 23100 McAuliffe Drive Robertsdale, Alabama 36567 251-972-6807 INTRODUCTION Storm Surge Storm surge is simply water that is pushed toward the shore by the force of the winds swirling around the storm. This adyancing surge combines with the normal tides to create the hurricane storm tide, which can increase the mean water level 15 feet or more. In addition, wind driven waves are superimposed on the storm tide. This rise in water level can cause severe flooding in coastal areas, particularly when the storm tide coincides with the normal high tides. Because much of the United States' densely populated Atlantic and Gulf Coast coastlines lie less than 10 feet above mean sea level, the danger from storm tides is tremendous. The level of surge in a particular area is also determined by the slope of the continental shelf. A shallow slope off the coast will allow a greater surge to inundate coastal communities. Communities with a steeper continental shelf bottom will not see as much surge inundation, although large breaking waves can still present major problems. Storm tides, waves, and currents in confined harbors severely damage ships, marinas, and pleasure boats. In general, the more intense the storm, and the closer a community is to the right-front quadrant, the larger the area that must be evacuated. The problem is always the uncertainty about how intense the storm will be when if finally makes landfall. Emergency managers and local officials balance that uncertainty with the human and economic risks to their community.
